HINGE ron. TILTING sAsH.

To all @07mm 'it'mag/ concern:

Be it known that I, JOHN WEBB, a citizen ofthe United States, residing atChicago, `in the countyof Cook and State4 of Illinois, have invented certain new and useful- Improvements in Hinges for Tilting Sash, of whichthe following is a specification.

ln tilting sash and particularly in that Y type adapted to close automatically to prevent the spreading Iof fire it is usual to provide a stop for limiting the angular swing of the sash and many forms` of construction 1 have been suggested` for this purpose.

Where the frame and sash are made of metal, however, such stop, if formed as an integral part of the window construction, as a lip or an olfset therefrom, is of insuflicient rigidity and strength and is often associated witha weakening ofthe frame or sash.

The objects of the present invention are to provide a stop construction of great rigidity and strength, unyielding and not subject to malformation or` other injury `by the rough usage to which thestops are subjected in the hasty or careless opening and inthe violent closing of suchwindows as when in case of fire or other emergency the retaining rmeans is released and the sash allowed to slam to a'closed position. Preferably, with these 'objects in view, the stop is independentof the frame or sash, is firmly attached thereto, and is of heavy` solid `construction such as cast metal, serving 'the function of and assisting toclose the sash by its own weight as well as to limit the opening and closing movement.. and to relieve the window of the jar incident thereto.

` In t-he accompanying,drawing and -in the description based thereon" are set forth preferred and modified embodiments of the invention. As, however, the same is capable of embodiment-in other and varied constructional forms the drawing and description are to be construed in an illustrative sense and notas unnecessarilyllimitingthe invention. v

In the drawing: Figure'l is a front elevation of a fragment of a window frame and sash provided with theimproved stop device; Fig. 2 is a vertical section on theline 2 2 of Fig. 1; Fig. 3 is a-transversesection on the line 3 3 of Fig. 1,; Fig. 4 is a detail in` perspective showing the trunnion device specification of Letters Patent.

ofthe frame by means of 'screw headed bolts 15, 15 which extend through the front wall of the frame and also through a reinforcing cast me-tal plate 16 mounted within the frame against the front ywall thereof.

The plates13 and 16 being securely clamped in assembled relation with each other and with the front wall of the frame by means of nuts '17, :17 threaded upon the inner ends 0f the bolts 15.

- A. trunnionv plate 18 is `firmly mounted upon the front face ofeach side of thesash 12 by means of screws 19 passingthrough `the front wall ofthe sash into engagement with a filler block 20 within the sash.y The kscrew holes inthe trunnionplate are formed as elongated slots 21 which provide for ver- `tical adjustment of thesash to'fit correctly within the frame. The plate 18 has cast as an integralpart thereof atrunnion 22 having a cylindricalfjournal 23gadapted to iit within'the journal bearing 14 and also having beyond lthe cylindrical portion a'squared portion 24 and beyond that a reduced threadedvportion 25 toreceive the nut'26. Theend face of the trunnio'n is flattened at 27 in order to facilitate the adjustment of the same 23. Immediately alongside the plate 13, the front wall of the window lframe 11, and also the reinforcing plate 16 are slotted at 28, the slot 28 lying-in a plane with the squared portion 24 of the trunnion.

A stop arm 29has at one end a square opening by means of which it is mounted upon the squared portion 24 of the trunnion' soas to be' firmly fixed against relative anguiar movement and to swing with the sash in the tilting of the latter. Throughout the greater portion of its length the arm is flattened or narrow as shown at 30, while the closed position.

terminal portion of the arm is provided with a broad hat face 3l lying in. a vplane at substantially right angles to the plane of the narrow portion 30 and adapted to engage against the rear wall of thefraine in oontact with the rear face of the reinforcing plate 16 as shown in dotted lines 2 when the sash is in its tilted position, the

arm occupying the position shown in full lines in said `ig'g'nre when the sash is in its lt will be observed that the narrow portion 30 of the arm plays within the slot 2S and the planeo-f this portion is parallel to thel plane 'of movement of the sash, whilettheplan'e of the broad flattened portion 31 is 'at rightfanfgle's'to the planeof the sash movement. yThe arm 929 is 'of east metal and vhas yeonsider'able 'weight which assists inlth'e olosing movement of the sash. The effective weight ofthefarm inaybe a'dvant ageouslyf augmented by providing y therein an 'opening 3Q and suspending therefrom a weight 33. The oint 'of'pivotal support oritne'fsaslfi being'od) the Vcenter thefsash will tend to ol'oseof its ownwei'g'htand this tendency is assisted by 'the :weight of the v-arm 29 and of th'e weight 33. f

p ln its closed lposition the joiirt between the 'frame and 'saslrisbridfged above the pivotal 'point .by the overlapping portion 84 of 'the fs'as'h, "and below the overlapping portion "355 "of 'the frame. Theseoverlapping portions iwoul'd theinseives act as stops to limit the Closing movement ofthes'ash, but

bei-nger sheet inetal are insufficient Yto long withstand the `jar of th'e Closing sash and serve in the present ease rather means for 'closing the ljoint between 'the sash and l traine than as stops.
